Rhipsalis 'Red Coral' is a captivating variety of the Rhipsalis genus, commonly known for its distinctive, vibrant red stems which give it its name. This epiphytic cactus, often found in tropical and subtropical regions, is a popular choice for indoor gardens due to its unique appearance and low maintenance requirements. Here’s a detailed description and care guide to help you keep your Rhipsalis 'Red Coral' thriving.

Description

Rhipsalis 'Red Coral' has long, slender branches that cascade elegantly from its base, making it ideal for hanging baskets or high shelves. The stems are initially green but can develop a striking reddish hue when exposed to bright light or cooler temperatures. During its flowering period, typically in late winter or early spring, it produces small, white or pale pink flowers, adding to its ornamental appeal.

Care Guide

Light

This plant thrives in bright, indirect light. Direct sunlight can scorch the delicate stems, so it’s best placed near a window with filtered light or in a well-lit room without direct exposure to the sun. East or north-facing windows are ideal locations.

Water

Water your Rhipsalis when the top inch of the soil feels dry to the touch. It's important to ensure the plant is in well-draining soil to prevent root rot. During the winter months, reduce watering to prevent the plant from sitting in too much moisture.

Temperature and Humidity

Rhipsalis prefers a warm climate with temperatures between 18°C to 24°C (65°F to 75°F). It can tolerate brief drops in temperature but should be protected from anything below 10°C (50°F). High humidity levels are beneficial but not essential. If your home is dry, especially during winter when heating systems are on, consider using a humidity tray or a room humidifier to increase moisture in the air.

Soil

A well-draining potting mix is crucial. An ideal mix could be one part orchid bark, one part coarse perlite, and one part peat moss. This will ensure adequate drainage and mimic the plant’s natural epiphytic growing conditions.

Feeding

Feed with a balanced, water-soluble fertilizer diluted to half strength once every month during the growing season (spring and summer). Avoid fertilizing in winter when the plant's growth naturally slows down.

Pruning and Repotting

Prune any dead or damaged stems to encourage new growth and maintain a neat appearance. Rhipsalis 'Red Coral' typically needs repotting every two to three years or when the plant outgrows its pot. Repotting in the spring is preferable, as the plant will be entering its active growing phase.

Common Issues

Watch out for signs of overwatering such as soggy soil and wilting or yellowing leaves. Pests like spider mites and mealybugs can occasionally be a problem; treat infestations promptly with appropriate insecticidal soaps or neem oil.

By following these care instructions, your Rhipsalis 'Red Coral' should remain a vibrant and attractive feature in your home or garden for many years.
